Description

Technical Field

[0001] This utility model relates to the field of furniture processing technology, and in particular to a drilling device for solid wood furniture. Background Technology

[0002] In existing solid wood furniture board drilling processes, the simple support structure on the workbench fails to effectively support the bottom of the board, easily leading to cracking and deformation due to uneven stress during drilling. This affects the overall stability of the workpiece and the quality of the finished product. Furthermore, existing equipment generally lacks a stable guiding mechanism, making it difficult for the drill bit to maintain verticality and straightness during drilling. This results in hole misalignment or rough hole walls, making it difficult to meet the precision and smoothness requirements of high-quality furniture manufacturing, leading to a low processing pass rate.

[0003] Furthermore, in the chip removal and cleaning processes, existing technologies mostly rely on natural fall or simple air extraction. Chips generated during drilling are easily trapped inside the hole, which can scratch the hole wall and cause blockages, affecting drilling efficiency. At the same time, the drill bit generates high temperatures during high-speed rotation. Without effective cooling and cleaning, the drill bit's lifespan is significantly shortened, requiring frequent replacements or manual chip removal. This not only increases the workload of operators but also severely reduces processing efficiency and the equipment's continuous operation capability. Utility Model Content

[0004] The purpose of this utility model is to address the aforementioned shortcomings in the existing technology by proposing a drilling device for solid wood furniture.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A drilling device for solid wood furniture includes a workbench with a through hole at the center. A lifting mechanism is provided at the top of the workbench, and a plate is installed at the working end of the lifting mechanism. An electric cylinder is fixedly installed at the top of the plate. The telescopic end of the electric cylinder passes through the plate and is fixedly connected to the plate. A drilling device is installed on the plate, and a drill bit is detachably installed at the working end of the drilling device.

[0007] Preferably, the top of the through hole is provided with a protrusion, which is used to support the solid wood furniture board to enhance its strength.

[0008] Preferably, the lifting mechanism includes two electric cylinders 1 fixedly installed on the top of the workbench and arranged symmetrically. The telescopic ends of the two electric cylinders 1 are fixedly connected to the plate 1. Several limiting rods are also fixedly installed on the workbench. The limiting rods are slidably connected to the plate 1 and used to limit the position of the plate 1.

[0009] Preferably, the drill bit has an internal air passage that runs vertically through it. The top of the air passage is connected to high-pressure air via a rotary joint, and the bottom has multiple air outlets.

[0010] Preferably, a drill sleeve is fixedly connected to one side of the lower end of the second plate via a connecting rod, and the drill sleeve is movably sleeved on the outside of the drill bit.

[0011] Preferably, the drill sleeve has a cavity inside, a blower is rotatably installed at the top inside the cavity, a screen plate is fixedly installed at the bottom inside the cavity, the bottom end of the blower is located below the screen plate and is fixedly connected to a first cutter, the lower end surface of the screen plate is fixedly connected to a second cutter, the first cutter and the second cutter are staggered, and an air extraction pipe communicating with the cavity is fixedly installed on one side of the top of the drill sleeve.

[0012] Preferably, a brush is detachably mounted on the lower end of the drill bushing, the brush being used to clean the surface of the drill bit.

[0013] Compared with the prior art, the advantages of this utility model are:

[0014] 1. This utility model effectively improves the overall strength of the solid wood furniture board by setting a protrusion to support it on the workbench. During the drilling process, it can prevent cracking or deformation caused by uneven force, ensuring the stability of the workpiece during processing. At the same time, the drill bushing supports and guides the drill bit, ensuring the verticality and straightness of the drilling, thereby improving the processing accuracy and smoothness of the hole wall.

[0015] 2. In this utility model, the drill bit completes the drilling operation under the drive of the electric cylinder. The rotary joint at the top introduces high-pressure air into the air passage and sprays it out from the air outlet. The high-pressure airflow blows out the debris in the hole in time, effectively preventing the debris from scratching the hole wall. At the same time, the airflow cools the drill bit, reduces the temperature rise of the drill bit, extends the service life of the drill bit, and improves the stability and reliability of the drilling process.

[0016] 3. In this utility model, the air extraction pipe and vacuum pump work together to generate negative pressure, which causes the debris in the hole and drill sleeve to be sucked away with the airflow, avoiding debris accumulation and blockage. The impeller is driven to rotate under the action of airflow, and together with the first and second cutters, it cuts large pieces of debris into small particles, ensuring that the debris passes smoothly through the screen plate and is extracted in time, maintaining smooth chip discharge and improving the continuous working capacity of the equipment.

[0017] 4. After drilling is completed, the brush automatically cleans the drill bit to remove residual debris and dust, ensuring that the drill bit remains clean for the next use. This design not only extends the service life of the drill bit but also reduces manual cleaning, improves work efficiency, and ensures the consistency and reliability of subsequent drilling quality.

[0018] In summary, this utility model achieves stable support, precise guidance, smooth chip removal, and drill bit self-cleaning during the drilling process through structural optimization and multi-functional synergy. It solves the problems of easy cracking of the borehole, easy scratching of the borehole wall, chip blockage, and drill bit contamination in the prior art, thereby effectively improving the overall quality and efficiency of drilling.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Reference Figures 1 to 4 A drilling device for solid wood furniture includes a workbench 1 with a through hole at the center and a protrusion 2 at the top. The protrusion 2 supports the solid wood furniture board to enhance its strength and prevent defects such as cracking and deformation during drilling. Two symmetrically arranged electric cylinders 3 are fixedly installed on both sides of the top of the workbench 1. The telescopic ends of the two electric cylinders 3 are fixedly connected to a plate 6. The extension and retraction of the electric cylinders 3 drives the plate 6 to move up and down. Several limiting rods are also fixedly installed on the workbench 1. The limiting rods are slidably connected to the plate 6 to limit the plate 6 and ensure its stability during the lifting and lowering process.

[0026] A second electric cylinder 4 is fixedly installed at the top of plate 6. The telescopic end of the second electric cylinder 4 passes through plate 6 and is fixedly connected to plate 7. A drilling device is installed on plate 7. A drill bit 8 is detachably installed at the working end of the drilling device. The drill bit 8 has an air passage 9 that runs vertically through it. The top of the air passage 9 is connected to high-pressure air through a rotary joint, and the bottom has multiple air outlets 11.

[0027] A drill sleeve 5 is fixedly connected to one side of the lower end of plate 2 7 via a connecting rod. The drill sleeve 5 is movably sleeved on the outside of the drill bit 8. The drill sleeve 5 has a cavity inside. A blower 13 is rotatably installed above the cavity, and a screen plate 14 is fixedly installed below the cavity. The bottom end of the blower 13 is located below the screen plate 14 and is fixedly connected to a cutter 15. A cutter 2 16 is fixedly connected to the lower surface of the screen plate 14. The cutter 15 and the cutter 2 16 are staggered. An air extraction pipe 10 communicating with the cavity is fixedly installed on one side of the top of the drill sleeve 5. The air extraction pipe 10 is connected to an external vacuum pump, so that when the blower 13 rotates under the action of airflow, it can drive the cutter 15 to rotate. With the cooperation of the cutter 15 and the cutter 2 16, the debris entering the cavity is cut. A brush 12 is detachably installed at the lower end of the drill sleeve 5. The brush 12 is used to clean the surface of the drill bit 8.

[0028] In this invention, a solid wood furniture board is placed on a workbench 1. A protrusion 2 located below supports the board to enhance its strength and prevent cracking or deformation during drilling. Electric cylinder 3 lowers plate 6 until the bottom of drill sleeve 5 contacts the workbench 1. Drill sleeve 5 provides support and guidance for the drill bit 8, ensuring the perpendicularity, straightness, and quality of the hole wall. Electric cylinder 4 lowers plate 7, causing the drill bit 8 to rotate and perform drilling. High-pressure air is introduced into air passage 9 via a rotary joint at the top of the drill bit 8 during drilling. The air is ejected from the outlet 11, blowing the debris generated during drilling out of the hole, reducing the scratches on the hole wall and improving the hole wall quality, and cooling the drill bit 8. The suction pipe 10 is connected to the vacuum pump to provide negative pressure. The airflow carrying the debris is sucked into the drill sleeve 5. The impeller 13 rotates with the airflow. At the same time, the first cutter 15 rotates and works with the second cutter 16 fixed on the screen plate 14 to cut the larger debris until the debris can pass through the screen plate 14. The debris is removed and blockage is prevented. After drilling is completed, the drill bit 8 is reset. The brush 12 cleans the drill bit 8 to ensure that the drill bit is clean enough for the next drilling to ensure drilling quality.
